Every two weeks, give your geraniums a balanced fertilizer, such as 10-10-10 or 20-20-20. Purchase water-soluble fertilizer for simpler application. Epsom salts, or magnesium sulfate, should be added to the plant water every third watering to deliver magnesium (1 teaspoon per 1 gallon). Alternately, you can plant the geraniums in the pot and add a slow-release fertilizer to the soil mixture to feed them all season.
The best fertilizer to use on geraniums?
Geranium fertilization throughout production is crucial for maximizing development, and fertilizer issues must be avoided by having a thorough understanding of full nutrition management.
A water soluble fertilizer is frequently applied by many growers. Although this is a fantastic way of fertilizing, it is crucial to apply enough water to ensure that each time you water, enough water drains or drips down the medium. Insufficient watering will cause a buildup of fertilizer salts in the medium. In many cases, the overall fertilizer content (soluble salts) of the medium will rise to levels that will significantly restrict plant growth.
200 to 250 ppm of nitrogen is typically advised for geraniums when fertilizing them continuously. Experience reveals that a continuous fertilizer program reduces nutritional issues.
Fertilizer kinds include 20-10-20 Peat-lite, 15-15-15 (Geranium Special), and 15-16-17 Peat-lite. EXCEL Limestone could be supplemented with Cal-Mag 15-5-15 to add Ca and Mg.
Fertilizer rates and methods: 150–200 ppm N using subirrigation or another constrained leaching scheme, or 200–250 ppm N constant liquid feed. Start fertilizing when you plant. observe pH and salt levels. Ivy geranium baskets without saucers can drain properly.

It has a well-balanced phosphate and potash composition that contributes to the soil’s high acidity level, improving soil quality and nourishing plant roots. The fertilizer is quite concentrated, but it’s simple to combine with water to create a solution that can be sprayed on plants every three to four weeks. Liquinox can also be used to promote improved general health and bigger, more frequent flowers in plants that are dormant or have just budded.
If you have serious blossoming issues, this is the best option. It doesn’t contain any nitrogen, so your plant will focus more of its energy on producing additional flowers rather than extending its leaves.
Does geranium fertilizer need to be specific?
Fertilizer is necessary for geraniums to blossom healthily, especially when they are grown in pots. Potted geraniums can’t collect nutrients from the soil like plants that are grown in the ground, so you’ll need to provide some.
Use a time-release fertilizer to feed your geranium once in the spring, or use an all-purpose granular fertilizer in the spring and summer. If the potting soil has fertilizer included, you won’t need to feed your plant at all for the first several weeks.
Instead, a water-soluble fertilizer like a flower and bloom plant food is beneficial for geraniums. Water-soluble fertilizers are trustworthy and simple to apply when combined in a watering can and administered every two weeks during the growing season.

They were all tall, lanky stalks with a few scraggly yellow leaves and a teetering fragment of red blossom on top that I can still clearly recall from childhood family vacations. They were in paint-peeling, boarding home window boxes. However, today’s most striking summer container displays are powered by pelargoniums (as we should properly refer to them), many of which are “collectibles for enthusiasts’ greenhouses and conservatory displays.”
Zonal pelargoniums, traditional geraniums with rounded leaves that frequently have a darker “zone or ring in the center,” are the preferred varieties for summer baths.
The shield-shaped leaves and sprawling habit of ivy-leaved pelargoniums make it nearly impossible to maintain a clean appearance in containers. However, they are fantastic for window boxes and hanging baskets. Balcon variants are proving to be very popular here as well. The Swiss balconies swear by them.
My favorite plants, regals, have almost orchid-like blossoms in beautiful colors like deep pink, pearly white, and almost-black maroon. The vintage variety “Lord Bute” stands out as being exceptionally unusual; its glossy black petals have contrasting pale pink rims. Although they are attractive enough to thrive on a sunny windowsill indoors, they are more sensitive and should be maintained covered on greenhouse staging or in a conservatory.
Then there are all the scented-leaved pelargoniums, which have flowers that aren’t particularly showy and don’t resemble typical types at all. They are raised for their fragrant leaves, which come in a variety of spices, including extra-strong peppermints, and all the citrus fragrances. These are excellent for growing somewhere you’ll brush by them because merely a minor injury will cause their scented oils to discharge. Grow them indoors as live air fresheners or include them in a tub of flowers on the patio.
A few varieties can be used in cooking, the majority can be used to make potpourri, and rose geraniums (P. capitatum, or Attar of Roses), are excellent for making homemade toiletries. As if that weren’t tempting enough, there are even tiny pelargoniums in both zonal and regal varieties. These can be used outside in summer containers, but where they look best is in lovely pot holders in the center of a garden table or piled high on a shelf in a greenhouse or conservatory.
Now is the time to purchase a wide variety of pelargoniums while supplies last. When you bring them home, plant them in three- or four-inch pots with a 50:50 mixture of peat-free potting soil and John Innes No 2 to give them the free-draining medium they prefer, and keep them on your sunniest windowsill.
If they don’t naturally spread out, cut each shoot off at the very tip to promote sideshoots. Each plant produces more flowers the more shoots it has. Additionally, “stopping,” as it is known, enhances plant form. Since excessive generosity results in the plants growing thick and green rather than blossoming wildly, water them sparingly and feed them lightly.
From July until the end of August, a mild tomato feed every two weeks will be beneficial. Simply inspect them once a week, take out any lower leaves that are yellow, and snap off any spent stems right before the petals fall. Start right away, and you’ll have everything you need to put on a world-class show that won’t stop until October.
How can I maintain healthy geraniums?
Gardeners have traditionally favored geraniums. They smell wonderful, are colorful, and are simple to grow. How to cultivate geraniums in your house and garden is provided here!
(Note: This page is about Pelargonium plants, sometimes known as geraniums or storksbills. This is not a page about “hardy geraniums, also referred to as cranesbills.
Geraniums are normally kept indoors to overwinter, even if they may be kept outside throughout the warmer months of the year. In contrast, if given enough light, they can bloom all year long indoors.
Geranium or Pelargonium? A Case of Mistaken Identity
Early in the 18th century, Dutch traders who were traveling through South Africa brought the plants that we now refer to as “geraniums” to Europe. Botanists misclassified these new plants into the same genus because they resembled the hardy wild geraniums that are already present throughout Europe.
Botanist Carl Linnaeus of Sweden included them in the genus Geranium in 1753. Pelargonium, which refers to the long, sharply pointed shape of their seedpod, was used to reclassify these new “geraniums when it was later revealed that they differed from European geraniums in the shape of their petals, the number of stamens, and other features.
However, people still refer to them by their old common name, “geranium,” even if we really mean “pelargonium.”
- You can grow geraniums as annual blooms or as indoor plants. They can be kept outside in a sunny area throughout the warmer months of the year (between your local frost dates).
- If keeping geraniums as indoor plants, make sure to do so in the late summer or early fall when overnight lows begin to consistently fall below 55F. (13C).
- Pay great attention to the size and color of geraniums when purchasing them. Healthy stems and leaves will not be straggly or discolored on top of them or underneath them. A plant with evident insect indications should also be avoided. Mealybugs, whiteflies, and spider mites are typical indoor plant pests.
- To prevent root rot, put plants in containers with drainage holes.
- When planting in pots, use a well-draining potting mixture rather than heavy, clayey soil. Geraniums dislike being planted in mucky, compacted soil.
- Place the plants where they will receive 4-6 hours of sunlight per day for the best bloom.
How to Care for Geraniums
- After letting the soil somewhat dry between waterings, water it again well.
- Water plants significantly less throughout the winter, but make sure the roots are not completely dried up. Given a time of hibernation throughout the winter, when they consume less water and don’t grow as much, geraniums thrive. For additional overwintering tips, see the section below.
- Regularly deadhead spent flowers to promote blooming.
- Pinch back the stems to encourage bushiness and prevent legginess.
- Fertilize approximately every two weeks throughout the active growing months. Half-strength a fertilizer that is water soluble When the plant should be dormant in the winter, avoid fertilizing.
- Repotting geraniums can be done in the spring to promote new growth or if they appear to need revitalization.
Overwintering Geraniums
- If they receive plenty of sunlight, geraniums that have spent the summer outdoors can be kept indoors. The sun may not be strong enough in northern regions in late winter to promote buds on some cultivars.
- Lift the plants before the first fall frost (you can find your local frost dates here), and use a sharp, clean knife to shapely prune the stems back to about 6 to 8 inches. In the low-sunlight environment they are about to enter, they shouldn’t have to maintain substantial amounts of leaves. A simple technique to increase the number of your plants is to save a few stems for rooting.
- Place the “mother plant” in the smallest pot you can find—just big enough to hold the roots—and fill it with ordinary potting soil.
- The plants should be kept in the shadow for a week before being moved to a sunny location and kept cool.
- Geraniums thrive in temperatures between 50 and 60 degrees Fahrenheit (10 and 16 degrees Celsius) at night during the winter, but they can also withstand lows of 32 degrees Fahrenheit (0 degrees Celsius) and highs of 80 degrees Fahrenheit (27 degrees Celsius), provided they are kept relatively dry.
- Cut off all the old leaves when the spring growth begins.
Keeping the new growth alive is the only challenge that can compare to getting it to appear. Here is some assistance with that:
- Only offer tiny quantities of water when the leaves begin to droop. Don’t feed or fertilize the plants. These plants must have some downtime.
- Pinch back your overwintered geraniums in February if you want them to bloom by Memorial Day. Take the plants outside and move them to beds or pots, as you like, once warm weather returns and all threat of frost has passed.
- Containers are ideal for growing the Common or Zonal Geraniums (Pelargonium x hortorum) (as well as outdoors).
- Hanging baskets, window boxes, and containers are all extremely popular places to use Ivy-Leaf Geraniums (Pelargonium peltatum).
How to Root Stem Cuttings
The majority of geraniums readily take root from stem cuttings when placed in soil, sand, water, perlite, or another rooting medium.
- Make a slanted incision 4 inches below the tip of the stem, above the node where the leaves emerge, with a clean, sharp knife. Cut the grass immediately below a node. Remove all except two or three leaves, any buds, and the stipules that resemble leaves at the base of leaf stalks.
- To ensure that the cut end of the stem will seal and not rot, roll the stem cutting in newspaper or place it in the shade for 24 hours.
- Place the stem in a wet rooting media container and keep it there for two days in a warm, shaded area. Give the cutting indirect sun after that. Just as needed, moisten the medium.
- Apply crushed geranium leaves to small cuts to halt the bleeding.
- Scarlet geranium is the flower that speaks of foolishness. More floral meanings can be found here.
- You won’t have to worry about those bothersome bugs because geraniums are known to be harmful to Japanese beetles.
- Keep geraniums out of the reach of curious youngsters and animals (cats, dogs) as they might cause indigestion or vomiting.
Low light, overexposure, and underwatering are common issues. Yellowing leaves are a sign that you are watering your plants either too little or too much. Try to water the geraniums evenly in this situation, and transfer them to a more sunny location.
